Roger Pau Monné d01d12de14 x86bios: use M_NOWAIT with mallocs 
Or else it triggers the following bug:

APIC: CPU 6 has ACPI ID 6
APIC: CPU 7 has ACPI ID 7
panic: vm_wait in early boot
cpuid = 0
time = 1
KDB: stack backtrace:
db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff826ff8d0
vpanic() at vpanic+0x1a3/frame 0xffffffff826ff930

While there also make x86bios_unmap_mem idempotent.
